# Bootstrap 5 Badges

> Bootstrap badge is small count and labeling components.

## Examples

Bootstrap badge scale to suit the size of the parent element by using relative font sizing and `em` units.

### Headings

### Buttons

Badges can be used as part of links or buttons to provide a counter.

Remark that depending on how you use them, badges may be complicated for users of screen readers and related assistive technologies.

Unless the context is clear, consider including additional context with a visually hidden piece of additional text.

### Positioned

Use utilities to modify a `.badge` and position it in the corner of a link or button.

You can also replace the `.badge` class with a few more utilities without a count for a more generic indicator.

## Contextual variations

Add any of the below-mentioned classes to modify the presentation of a badge. Please note that when using CoreUI for Bootstrap's default `.bg-light`, you'll likely need a text color utility like `.text-dark` for proper styling. This is because background utilities do not set anything but `background-color`.

> ##### Conveying meaning to assistive technologies
> 
> Relying on color to convey meaning creates a visual cue that assistive technologies, like screen readers, cannot perceive. It's essential that any information represented by color is either apparent from the content itself (e.g., the visible text) or supplemented by alternative methods, such as extra text using the `.visually-hidden` class.

## Pill badges

Apply the `.rounded-pill` modifier class to make badges rounded.

## Customizing

### CSS variables

Badges use local CSS variables on `.badge` for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

```scss
--cui-badge-padding-x: #{$badge-padding-x};
--cui-badge-padding-y: #{$badge-padding-y};
@include rfs($badge-font-size, --cui-badge-font-size);
--cui-badge-font-weight: #{$badge-font-weight};
--cui-badge-color: #{$badge-color};
--cui-badge-border-radius: #{$badge-border-radius};
```

### SASS variables

```scss
$badge-font-size:                   .75em !default;
$badge-font-weight:                 $font-weight-bold !default;
$badge-color:                       $white !default;
$badge-padding-y:                   .35em !default;
$badge-padding-x:                   .65em !default;
$badge-border-radius:               var(--cui-border-radius) !default;

$badge-font-size-sm:                .65em !default;
$badge-padding-y-sm:                .3em !default;
$badge-padding-x-sm:                .5em !default;
```
